These birds breed in Asia or the Arctic during the northern hemisphere summer, and set off to New Zealand before the northern winter sets in. Most arrive New Zealand in the southern spring (around September), and return in autumn (March to May) to their breeding grounds. Small numbers remain in New Zealand through the winter. These are mostly young birds, not yet ready to breed.
